We assessed inter-annual changes in fish assemblages of a tropical bay which experienced a heavily industrialized process in the last decades. A highly significant difference in community structure among the bay zones, and a decrease in fish richness and abundance over time were found. Changes in fish richness and abundance between the two first (1987–1988 and 1993–1995) and the two latter time periods (1998–2001 and 2012–2013) were sharpest in the inner bay zone, the most impacted bay area, and in the middle zone, whereas the outer zone remained comparatively stable over time. These changes coincided with increased metal pollution (mainly, Zn and Cd) in the bay and with the enlargement of the Sepetiba Port. Spatial changes in the fish community structure among the bay zones were related to differences in salinity, transparency and depth with this latter variable acting as a buffer stabilizing temporal community changes. 相似文献

Ambient suspended particles (TSP) were collected from January to June 2001 at seven sampling sites in western Macedonia, Greece,
where four thermal power stations are located. TSP samples were chemically characterized for minerals (Fe, Al, Mg, Ca, K,
Ti and Si), trace elements (P, Cd, Cr, Cu, Mn, Pb, V, Zn, Te, Co, Ni, Se, Sr, As, and Sb), water-soluble ions , carbonaceous compounds (OC/EC) and polycyclic aromatic hydrocarbons (PAHs). These classes of compounds were consequently
compared with PM mass concentrations of TSP in order to perform mass closure. PM chemical compositions exhibited differences
at the seven sites. Minerals were found to be more abundant at four sites, electrolytes dominated the composition at two of
the sites while carbonaceous material was most abundant only at one site. The fraction unaccounted for ranged between 22 and
34%. Spatial variations of atmospheric concentrations showed significantly higher levels of minerals, some trace metals and
TC at the site that was closest to the power plants. At the same site ions exhibited high correlations with minerals and the
majority of trace elements. 相似文献
